I've got an enhancement request to have it behave like extern(C):

Thoughts? Anyone use extern(Windows) on non-Windows systems?

What is the extern(Windows) is supposed to do differently on
windows than existing externs ?

It changes the calling convention and name mangling to match what Microsoft uses for the Windows API.

OK, but I don't get why you wouldn't be able to use
extern(C/C++/Whatever) and it adapt to the system. Obviously
there is something about windows that I'm not really aware of.

That's what it does now.

I'd doubt there's be anyone that uses extern(Windows) on non-windows systems, but there may be people who wish to force stdcall for whatever reason.  Currently, extern(C) on Windows could either be a stdcall, cdecl or thiscall function.

Honestly, I'd first deprecate/remove extern(Pascal), then think about
deprecating extern(Windows) later.

Even Microsoft gave up on stdcall for Win64 and uses the C convention.

I think that's because the 64 bit C convention is a lot closer to the stdcall convention anyway, putting more args in registers etc...

I just think that the purpose of having a separate Windows API calling convention no longer makes any sense. It dates back to the 16 bit world when Pascal had a different calling convention and a lot of people thought that was better.
